MAINTENANCE
METHOD FOR CLEANING AFTERCOOLER FIN
1.
Open engine side covers (1) on both sides of the machine.
2.
Clean them through the oil cooler fins (2) from both sides
of the machine.
3.
Blow off mud, dirt, leaves, etc. in aftercooler fins (3) with
compressed air.
Steam or water may be used instead of the compressed
air.
However, when performing powerful steam cleaning (high-
pressure machine washing) of the heat exchanger (after-
cooler), maintain sufficient distance from the machine.
If steam cleaning (high-pressure machine wash) is per-
formed at close distance, there is a danger that the internal
fins of the heat exchange equipment may be deformed,
and this will cause early clogging and breakage of the
equipment.

Perform the following check.
•
Check the rubber hoses. If they are cracked or fragile,
replace them.
•
Check the hose clamps for looseness.
